Eleven (11) new
high current - dual primary - stock transformers added to our line - perfect
for high power - tube filaments (February 2014)

We are
now quoting & building transformers to Peter
W. Dahl's original designs. (April 2013)

Peter
W. Dahl transformers to live on! A purchase agreement has been signed and executed
with Hammond Manufacturing Company, Inc. of Cheektowaga, New York to acquire the
Peter Dahl line of products from Harbach Electronics, LLC. Finalization of the
acquisition and transfer of assets will take place over the next few weeks with
the transfer to be completed by March 31, 2013. (February 2013)

Line
Isolation & Autotransformers, safely run equipment almost anywhere
in the world! Great for the bench & check out our slight step down units to
keep the stress off those older 110VAC receivers (Listed March, 2002).

AT-1500

In the early 1980's we
also produced Hammond R.F. linear amplifiers for Amateur (Ham) Radio use. Naturally
tube type, built for continuous duty, powered by Hammond "iron" &
housed in Hammond enclosures. We stopped production over 30 years ago. Even now
folks are still asking about them (many are still in active use today). Two versions
of two different models were produced:

In
the 1960's we sporadically offered the HL-500
(87K photo), HL-700 and HL-750 linear amplifiers
too. They used quad 811-A output tubes. Not only using Hammond "iron",
RF chokes and enclosures BUT also using our then available, air
variable condensers (PDF - 239K). Very little data on these amplifier
models has survived...

In
the late 1930's we designed audio amplifiers using our transformers & enclosures.
Thanks to Bill Crowther (of Winfield, B.C.) for locating these schematics &
sending them to us. Interesting to see a note on the 1247 & 1245 diagrams
regarding 25 or 60 cycle power use!

We
also made audio amplifiers & battery eliminators (again combining our enclosure
& transformer skills) in the 1920's! Check out a few pages from the fascinating
Aikenhead's Radio Catalog
(1929-1930) (PDF file 934K) - an early Toronto, Ontario distributor of
our products.
